In case anyone is interested, here's the full msieve log for 732541^471.

The new list of roadblock composites is here
http://www.lirmm.fr/~ochem/opn/mwrb2100.txt and the old one is here http://www.lirmm.fr/~ochem/opn/old_mwrb2100.txt Most of the changes are due to the recent factorizations of sigma(3^660) and sigma(732541^46). Notably, the weight of sigma(6115909044841454629^16) drops from 79580833 to 67959517 and the weight of sigma(127^192) drops from 29196565 to 14190689.

Are the files available that contain all the factors used in the proof?
How do you check that all the composites hit have been trial factored to at least the assumed level given that pfn doesn't output a file containing the composites hit(I suppose you could extract them from the log)? Does it even matter if there are unfound small factors in nonroadblock composites apart from them causing gcd errors?
